Oversized / Desert Tanks
When the next fuel stop is 200 miles away and the trail doesn't forgive shortcuts, an oversized desert tank is the difference between adventure and breakdown. Designed for long-distance off-road riding, enduro racing, and adventure touring, these high-capacity tanks extend your range well beyond factory limits — some offering two to three times the stock volume.
Our oversized and desert-spec tanks are built from rotomolded polyethylene for maximum durability against rocks, roots, and rough terrain. Brands like IMS, Safari, and Clarke engineer these tanks to mount directly to your stock subframe with minimal modification, so you spend less time wrenching and more time riding. Available for most major dirt bike manufacturers including KTM, Husqvarna, Honda, Yamaha, Kawasaki, and Suzuki.

Frequently Asked Questions
What is an oversized desert gas tank for a dirt bike?
An oversized desert tank is an aftermarket fuel cell designed to replace the small stock tank on motocross and enduro bikes to provide significantly more range for long-distance riding. Brands like IMS and Acerbis engineer these tanks to carry fuel lower between the shrouds, maintaining a slim ergonomic profile while increasing capacity for marathon off-road sessions.
Which dirt bike models are compatible with oversized fuel tanks?
Oversized tanks are available for most major manufacturers including Honda, KTM, Yamaha, Husqvarna, and Kawasaki. Specific fitments range from the IMS 3.0 gallon tank for the Honda CRF450R to the Safari 15L tank for the Husqvarna FE 501, ensuring fuel security for both modern fuel-injected and older carbureted models.
How do I choose the right capacity for a desert gas tank?
Capacity needs depend on your riding style, as a Clarke 3.4 gallon tank for a Yamaha YZ250F is ideal for local trails, whereas a 4.0 gallon or larger tank is necessary for competitive desert racing. Consider that more fuel adds weight, so choose the smallest oversized option that safely covers your longest planned distance between fuel stops.
Are IMS, Clarke, and Safari tanks better than stock fuel tanks?
Aftermarket tanks from IMS, Clarke, and Safari are constructed from high-density cross-linked polyethylene, making them more durable and impact-resistant than many OEM units. These brands specialize in desert-specific geometries that optimize weight distribution, often allowing riders to carry 1 to 2 extra gallons without drastically widening the bike.
Does an oversized tank require a different seat or fuel pump?
Most oversized desert tanks are designed to work with your stock seat, though some extreme capacity models may require minor trimming or a specific aftermarket seat base. When installing a tank like the IMS 3.4 gallon for a KTM 500 EXC, you will typically transfer your OEM fuel pump or petcock directly into the new tank using the provided O-rings and hardware.
